R/stat_position.R
stat_position.Rd
It is usually not called directly by user but mainly used by compute_stats function (which is called by ggcyto add method when geom_states layer is added).
stat_position(gate, ...) # S3 method for filter stat_position( gate, negated = FALSE, adjust = 0.5, abs = FALSE, data_range = NULL, limits = NULL, ... )
gate | a flowCore filter |
---|---|
... | other arguments |
negated | logical indicating whether position needs to be moved to negative side of gate |
adjust | adjust the position of the centroid. This can be a length-2 vector with an adjustment in each dimension. |
abs | logical |
data_range | a two-row data.frame representing the actual data range. Each column is a a range for a specific channel. First row is min, Second row is max. |
limits | used to fix the gate range |
a data.table of gate centroid coordinates
